APPARATUS; FOR BAKING PASTRY CON'ES.

Patented Nov. 11,1913.

rying any desired number of conic cores 10, and of a plate 9 carrying a corresponding number of molds 11 to receive said cores, lea'ring'a small space between each mold and its core for the dough or pastry to be formed and baked in. Said journals are arranged at opposite edges of the plates and are longitudinally divided into semi cylindrical half journals, 7 on the core plate and 7 on the mold plate.

Each half journal on the core plate has its end formed with a projection 12, which in Figs. 1, 2 and 9 is shown to be angular and preferably slightly fiat in cross section and projecting beyond the end of journal 7; and the latter half journal has its normally lower side provided with a hook 13 adapted to engage a pin 14lfixed in the side of the stove casing (as best shown in Fig. 6), this is to prevent raising of the mold plate when the core plate is raised as the baked pastry may cause the plates to stick together. The core plate is raised and lowered by the lever at, which in Figs. 1 and 2 is shown as a double or U-shaped lever fulcrumed at 16 to brackets 17, which project from the rear side of the stove casing and may have lugs 18 for the lever to lean rearward against when the device is fully opened. In a less open position the lever. may be sup ported by a prop 19, which is pivoted at 20 and provided with a weight 21, that tends at all times to swing the prop with its notch 22 into supporting engagement with a pin 23 fixed on the lever. This prop holds the lever with the core plate in an inclined position a little higher than indicated in dotted lines in Fig. 2, which is a handy position for removing the pastry cones from the cores,

where they usually stick some. hen the lever is to be lowered again the operator grasps with one hand the handle bar 4: of the lever and with the'other hand he takes hold of the pin 24 of the prop and swings it slightl forward so he can lower the lever. At the front side of the stove casing is a single bracket 25, whose end may form a ban-- then applied to produce a greater pressure during the rest of the baking process, the plates being turned over with core plate downward before the greater pressure is applied. The baking usually takes only from one to two minutes, after which the core plate is again turned to the top, the hook 28 disengaged, the lever and core plate raised, the baked cones or cups removed and after new dough-has been placed in the molds the gc re plate is again brou ht down, the lever docked by the hook and the process repeated.

Each side bar of the lever has a shallow notch 32 at the point where it presses upon the journal, and'adjacent thereto it has a hanger 33 (best shown in Fig; '2) extending downward beyond the endof journal 'T and provided with a deep notch 34, which during the raising of the lever engages the bottom and sides of the projection 12 and then raises the coreplate away from the mold plate and brings the former to an inclined position.' When the core plate is again lowered the hanger moves with its notch 34: low enough to permit the journals to rotate. The rotation or. turning up side down of the plates may be done by any suit able handle liked to one of the plates or their journals, in Figs. 1, 2 and 9 I have shown an arm 35 serving that purpose, it is fixed on the mold plate and adapted to rest upon the edge of the stove casing at either side of it, or if the stove casing is too high for that it may have notches 36 for the arm; said arm islong enough to act as a hand lever in turning the plateseven while the lever presses. on them.

37, are dowel plus to help bring the plates 3 and cores in correct position.

In the modification in Figs. 4-, 5, 6 and 7 is shown a form in which'the stove casing is of sheet iron or otherwise too weal: to stand the working of the lever. The latter is fulcrumed to two posts l7 and the front bar i is held down by a post l7 on which the hook 28 is mounted at 27 and pressed by spring '25. The dog or book is alsoniodified by having a handle 38 by which it may be manipulated. The handle may also act as a weight, and make spring 25 superfluous' Also the lever is slightly modified by having a handle 39 with a pin 40 for the hook to enline position'l2 in Fig. 6 and then back to.

the fullline position when the core plate is to be raised by the hanger. It will be seen also that this arrangement enables the method.

molding device to be rotated half a turn, ahd still the core plate when in proper position to be lifted, is for that purpose connected with the lever; In this case thehanger has an upward bulge 41 to prevent escape of the journal and the projection 12= -is se mental in cross section, forming a groove ?or said bulge; but it is obvious that also this opensided hanger could have a notch like 3d and the journal could have a' projection 12 the same as in Fig. 2. The advantage in Fig. 6 is that the lost motion in Fig. 2 is avoided, but on the other hand the notch 34 insures a more firm position of the core plate while it is away from the mold plate. In Fig. 5 a kind of hook 143 is shown instead of a pin 1a in Fig. It will in some cases be preferable to the pin.

In the modification in Fig. 9 the lever is fulcrunied at 42 intermediate its ends to a post 43, which post and a post 44: and top bar-45 make a kind of guiding frame, from which extends a lever keeper do with catches 47, 4:8 for the lever to engage above and below respectively. In suitable guides 49 on the 'bar l5 slide two vertical rods 50, to whose lower ends is fixed a bridge bar 51, having downward bent ends 52 pressing upon the journals 77. To said angular end 52 are secured the hangers 33, or they may be of the modifiediorm 33". In this instance the inner end of the hand lever is connected by a link-53 to the middle of the bridge bar or presser bar 51.

In the operation of. the form in Figs. 9 and 10, the gentle pressure on the plates is caused by swinging levers: upon the shoulder 54 and the greater pressure by forcing the lever upon the higher shoulder 55. When the core plate is raised considerably above the mold plate for thQIQITlOVEll of the baked cones, the core plate does not incline, the lever is thrown underneath the catch 48,

which being hook-shaped prevents accidental escape of the lever and dropping of the core plate while the pastry cones are being removed therefrom in any suitable man- 'ner, one ofwhich is to place a shallow box below the pastry cones while bringing the lever down to the position 56 in Fig. 10 and makea light blow with it upward against the catch 48; this will ordinarily cause the pastry cones to drop into the box. The operation of the other forms has already been described. The paste or dough is put into the molds by any suitable means and The gas burner shown, or any other suitable means will furnish the heat for the baking. In Figs. 6 and? is shown at 2- how the journals may rest on post which do not form an entire stove casing, and in Figs. 3 and 9,2 indicates thin, cheap sheet metal used as a guard about the flame w aile the journals rest in the firm posts adja'cen thereto.

. tion made integral with the ever, need not to be open above the journals they engage, and said journals 7 of the core plate 8 are cylindrical in the hangers but farther in they are half-round so as to form cylinders when together with journals 7 and to rotate with the latter in the bearings and receive pressure from the main lever, (as best shown in. Fig. 14 The ournals 7 are preferably loosely fitted in the hangers, so as not to resist the lever when it is to press upon .the journals of the mold plate when the latter is turned upward. In this case-the plates are rotated, by a small lever 35", which is fixed on one of the journals 7" and engages in anotch 57 in a springy arm 58 fixed on the main lever, the arm having a shoulder 59 to stop the -motion of the small lever when the core plate is in its proper upward position for separation from the mold plate;' when the core plate has been raised and It is lowered again into baking position and the two plates are to be turned, the lever 35 is simply turned downward, the springy arm yielding and letting it escape from the notch automatically.

In Fig. 14 is shown how the lever 35 may have a horizontal arm'or-handle 60, which makes it a crank that is very handy for quick turning of the plates. The advantages of the'modifications shown in the last three figures are, that when the mold plate is upward the lever will readily lift both plates together and give access to the interior of the stove when so desired; also that there is practically no lost motion between the hangers and the journals of the core plate, and further, that the considerable length of the leveror crank portion 35 from the journal to the springy arm causes the. core late to be held in more accurate posior return to the mold plate than any of the other means shown could give it.

It is obvious that the forms of hangers and journals and turning means shown in the last three figures are applicable also with the bar 51 in Fig. 9, especially-since it, is evident that said bar may to good advantage be secured across any of the levers shown outside of the form in Fig. 9, and most readily so to lever 4", as the ends of bar 51 may carry any form of hangers.
